SFML Window not showing!!!

[Tex Killer]

Viruses, try adding one extra line of code:

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{

    sf::VideoMode vmode(800,600,32);
    sf::RenderWindow Window(vmode, "Animation Training");
    Window.EnableVerticalSync(true);
    ...

Still flickering..

YES i FINALLY GOT IT NO FLICKERING A PERFECT ANIMATION! The problem was that i was actually drawing a subrect that was out of bounds of the spritesheet which meant it came up blank. Heres the updated code:

Code: [Select]


#include <SFML/Graphics.hpp>



int main()
{
    sf::RenderWindow Window(sf::VideoMode(800,600,32), "asdsad");

    sf::Clock clock;

    sf::Texture pic;
    sf::Sprite sprite;
    int frame,frame2;
    frame = 0;
    frame2 = 0;

    pic.LoadFromFile("SpriteSheet.png");

    sprite.SetTexture(pic);

    while(Window.IsOpened())
    {
        sf::Event Event;

        while(Window.PollEvent(Event))
        {
            if(sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape))
            {
                Window.Close();
            }


        }

            Window.Clear(sf::Color::Cyan);

            if(clock.GetElapsedTime() >= 100)
            {

                sprite.SetSubRect(sf::IntRect(frame * 128,frame2 * 128,128,128));

                ++frame;

                if(frame == 4)
                {
                    frame = 0;
                    ++frame2;
                }

                if(frame2 == 4)
                {

                    frame2 = 0;
                }

                clock.Reset();

            }





            Window.Draw(sprite);

            Window.Display();








    }


    return 0;
}


So you see i put frame == 4 and frame2 == 4 instead of frame and frame2 == 5. So now i was drawing the frames in the actual sprite sheet, not a subrect beyond it. Thanks for all advice i extremely appreciate it!

Congratulations on solving your own error.  
Keep practicing and that will be very common.

Good job; that's what I was trying to tell you .

[Viruses]

@Pyrius   Lol sorry shoulda looked at your advice more carefully   But thanks! Any ideas on how to make my OWN spritesheet?

[Tex Killer]

Well, the simplest way would be with paint, but there is also photoshop and a lot others.

By the way, I still recommend you to enable vertical sync, as it would limit the frame rate to the maximum supported by the monitor, avoiding useless processing and image tearing.

For a walking animation, this is helpful: http://www.manningkrull.com/pixel_art/tutorials/walking.asp. Don't copy it exactly, though, make your own character and follow the general idea. If you copy the legs pixel for pixel with different colors, you won't learn much.

Okay..Does anyone know of a site that has actually good sfml tutorials? Ive searched soooo much and all of the sites explain NOTHING.. I sort of know the basics but i still want to learn more about the sf namespace and such..and dont say documentation because its not like that explains it well.

[Tex Killer]

The documentation works just well for myself. What do you expect?

By the way, there is a tutorial on making a complete game here: http://www.gamefromscratch.com/page/Game-From-Scratch-CPP-Edition.aspx

[Viruses]

Ive already tried that website...

[Tex Killer]

So, what happened? Why are you asking for other?

[Viruses]

Umm nvm.. I have a problem with coding. So, so far ive been coding in one file, the main.cpp . But ive noticed that when i was programming a game, it got way too confusing for one file. So then i made a class named Player. So now i had Player.h and Player.cpp . There were so much problems that i encountered. I want to organize it is that i will have the functions of Player all in that class. So Move() for example. Display() to display the player. But in order to display the player, you need a renderwindow object . Now this is where i got errors. When i put that Display() took an arguement of sf::RenderWindow()   (i did this arguement because in the main function i would pass my renderwindow object that id already made into the parameters) and therefor it would draw it. But in the header file of Player,   i dont know how to define a function that takes that arguement. I tried putting this:

Code: [Select]

 

void Display(sf::RenderWindow(sf::VideoMode(int,int,int), string);



Then in player.cpp i did this:

Code: [Select]



void Player::Display(sf::RenderWindow(sf::VideoMode(int,int,int), string);




The reason i put int int int and string is because the videomode takes those arguements and the string is for the title. So i got errors. Basically what i need is a way to organize my code into different files. Thats the whole thing. I just gave the above because its the main problem im having is putting variables of sf into the files..Thanks in advance!

That is some pretty fundamental C++ stuff you need to pick up here, people on this forum might be able to help you, but truth of the matter is you are asking the wrong people.

I would suggest you run through a tutorial or two, or pick up a book.  You need to get a bit more comfortable with the basics of C++ before you are really ready for SFML.  Try any of these resources, the free ones will get you started, although I highly recommend the C++ Without Fear book if you are willing to outlay some cash.  It's one of the best beginner books I've read, although I sped read it as a non-beginner.

Lol ive been through more than 73 tutorials, a book, and other websites and you saying i have to learn the basics.. This is probably one of those things that werent taught so.. and this has to do with sfml. the sf::RenderWindow() parameters..
